Hmm, I might be missing something obvious, but here’s the best I can come up with. First, specify that you want the tag search to sort based on timestamp, earliest first: (add-to-list 'org-agenda-sorting-strategy '(tags timestamp-up)) Then make a custom function that when called on a heading returns the first timestamp: (defun my/org-get-first-timestamp () (save-excursion (or (and (re-search-forward org-ts-regexp (save-excursion (outline-next-heading) (point)) t) (match-string 1)) ""))) (Org might already have a function that would do that, but that seems to work.) Now use that function in the agenda prefix for tag searches: (add-to-list 'org-agenda-prefix-format '(tags . "%-21(my/org-get-first-timestamp) ")) With the example you gave---but changing 2018-11-1 to 2018-11-01 to make a valid timestamp---‘C-c a m client1’ gives me: Headlines with TAGS match: client1 Press ‘C-u r’ to search again 2018-10-28 Tue description of deadline :client1: 2018-11-01 Thu 10:00 a meeting :client1: -- Kyle
